Long Answer Type Questions
• A non-metal A which is the largest constituent of air, when heated with H, in
1 : 3 ratio in the presence of catalyst (Fe) gives a gas B. On heating with
0,, it gives an oxide C. If this oxide is passed into water in the presence of
air, it gives an acid D which acts as a strong oxidising agent.
(a) Identify A, B, C and D.

Answer:
(a) A is nitrogen; because nitrogen is the largest constituent of air. B is ammonia, C is nitrogen dioxide and D is nitric acid (nitric acid is a strong oxidizing agent).
When nitrogen is heated with hydrogen in the presence of a catalyst, following reaction takes place:
N
2
+3H
2
→2NH
3
When nitrogen is heated with oxygen, we get nitrogen dioxide
N
2
+2O
2
→2NO

When nitrogen dioxide is treated with water, we get nitric acid
NO

+H

O→HNO

(b) This non-metal belongs to Group 15.
